Voltage Input

Most industrial and scientific measurement applications try to use a physical principle underlying a sensor in such a way that the physical properties of a process result in a corresponding voltage or current signal that is easier to handle and process. This is usually a voltage or current signal.
The voltage signal can be amplified, scaled, filtered or linearized by means of an analog circuit or converted directly into a digital value with our VI01 Octal Voltage Monitor. Any mathematical post-processing including scaling, linearization or calibration can be conveniently performed in software.

Voltage Output

Actuators or controllable power supplies are usually controlled by analog signals. Many of them use the input voltage range of 0 to 10 V or -10 to 10 V to control the total output range. For the input signal, most applications use control loops such as PID controllers, which can be implemented in hardware as well as in software.
The VO01 Octal Voltage Output Device provides eight independent analog voltage output channels ranging from -10 V to 10 V. The 16-bit digital-to-analog converters and sophisticated temperature compensation methods ensure highest accuracy, low noise, high signal stability and lowest thermal drift.

VI01 Octal Voltage Monitor

The VI01 device is a versatile and easy-to-use voltage monitor. With eight inputs, it can be used with any industrial transducer with the voltage output ranging from -10 V to +10 V. The ultra-low noise, the high resolution and the outstanding accuracy make it ideal for industrial applications as well as for scientific experiments.
The channels are multiplexed, amplified, conditioned and sampled by the high-performance 24-Bit delta-sigma A/D converter. This ensures maximum data acquisition rates of up to 3 kHz at lowest noise levels. Since the channels are sampled alternately, the acquisition rate per channel depend on the number of selected channels.
